We just moved into a new house and turned on the Toyotomi…

Customer Question

We just moved into a...

We just moved into a new house and turned on the Toyotomi instant water heater. Now we have hot water ONLY in the house. Every faucet and even the toilet tank.The pipes are right next to each other so we thought perhaps that was the problem. But the intake pipe of cold water from the well to the water heater is also warm. Which makes it seem like the heater is pushing lots of hot water back into the cold lines.The shower started out hot and turned lukewarm after about 5 minutes.We turned the whole thing off for now. Worried about the implications of this issue. The old owner of course is not answering his phone. Any idea what’s wrong here and how to fix it?

Okay. Sounds like we have hot mixing with the cold. Is there hot water tank at all?

Any recirc pump?

This is a photo of what’s above the unit. The hot water is on the left and cold water intake on the right. The pipes enter the house side by side along the ceiling in a soffit and then drop down to the kitchen and on to the bathroom.

Alright, so we don’t see any recirculating pump which seems odd. It does not say that it has a tank it in, just says instant on it. But it is quite big. Not sure what you mean about the hose with hot and cold water.. where would we look for that?

I don’t see anything in the room that would allow it to mix. The water line is cold where it comes in from the well but then hot once it gets to the water heater and everywhere past that. Is it likely there is a valve broken inside the water heater that is allowing hot water to be pushed through both the cold water intake and hot water outlet?
